Technical Field

[0001] This utility model relates to a rotary positioner, belonging to the field of lifting equipment. Background Technology

[0002] In many industrial production sectors, especially in heavy machinery manufacturing, it is often necessary to assemble and process large workpieces. Traditional manual operations are not only inefficient but also prone to damaging workpieces and causing personal injury.

[0003] Existing automatic positioners often suffer from problems such as poor stability, complex operation, and low positioning accuracy; moreover, existing automatic positioners often require a special frame for fixing large barrel-shaped components, resulting in low versatility. Utility Model Content

[0004] In order to overcome the technical problems in the prior art, this utility model provides a rotary positioner.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A rotary positioner; comprising:

[0007] The flipping mechanism includes a flipping seat, one end of which is fixed to a rotating seat. The rotating seat is rotatably connected to a support. A pusher seat is also provided on the flipping seat. A linear pusher mechanism is provided between the pusher seat and the support. The flipping seat pushes the relative support to flip through the linear pusher mechanism.

[0008] The fixing mechanism includes a fixed disk, the center of which is rotatably connected to a tilting base via a rotary table. A main rotary motor for driving the rotary table is installed within the tilting base. Several jaw assemblies are arranged in a circular array on the fixed disk. Each jaw assembly includes a sliding guide rail within the fixed disk, with jaws slidably connected within the guide rail. Each jaw has a support rod for supporting the workpiece. A lead screw is installed within the guide rail, with both ends rotatably connected to the ends of the guide rail. A drive gear is installed at the end of the lead screw. A threaded sleeve meshing with the lead screw is installed within each jaw. A lead screw drive motor is fixed within the rotary table, and a drive gear is fixed to the motor shaft of the lead screw drive motor, with the drive gear meshing with the drive gear.

[0009] As a further improvement of this utility model, the bottom of the support rod is fixed to the claw by threads, and a positioning plate is connected above the fixing plate through the support rod of each claw. The positioning plate is provided with a positioning groove for the support rod to pass through, and the end of the support rod is fixed to the positioning plate by a clamping nut.

[0010] As a further improvement of this utility model, a support sleeve for supporting the inner wall of the workpiece is provided on the surface of the support rod.

[0011] As a further improvement of this utility model, a rotating groove is provided on the surface of the rotating base, and a conductive protrusion ring is provided at the bottom of the rotating groove. A brush is provided on the outer ring of the conductive protrusion ring. A conductive connecting ring extending toward the conductive protrusion ring is provided at the bottom of the rotating table. A conductive ring made of conductive material is provided on the inner ring of the conductive connecting ring. The conductive connecting ring is located on the outer ring of the conductive protrusion ring, and the brush is in contact with the conductive ring. The brush is connected to the power supply through a terminal provided on the rotating base.

[0012] As a further improvement of this utility model, a first needle roller bearing assembly is provided in the rotating groove, and the bottom surface of the rotating table is in contact with the first needle roller bearing assembly.

[0013] As a further improvement of this utility model, the fixed plate includes several sets of swing arms, which are integrally fixed to each other. A sliding guide rail is provided inside the swing arm, and the swing arms are supported by each other through connecting ribs.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model achieves the technical function of traditional positioners, which can only adapt to small cylindrical workpieces and cannot adapt to various cylindrical workpieces of different specifications, by setting up a support system with a jaw mechanism and in conjunction with a hydraulic tilting mechanism.

[0016] The positioning plate can reduce the end bending moment of the support rod and improve the stability of the support.

[0017] Support sleeves can increase the strength of support rods and reduce the pressure on the inner wall of workpieces.

[0018] The rotating slot can not only have a built-in rotating conductive mechanism that achieves electrical connection during rotation through brushes and conductive rings, but it can also add an additional bearing support structure to improve stability.

[0019] The fixed plate is supported by connecting ribs, which makes it stronger. Attached Figure Description

The flipping seat pushes the relative support to flip through the linear pusher mechanism.

[0028] like Figure 1 and Figure 2 The fixing mechanism includes a fixed disk, the center of which is rotatably connected to a tilting base via a rotary table. A main rotary motor for driving the rotary table is located within the tilting base. Several jaw assemblies are arranged in a circular array on the fixed disk. Each jaw assembly includes a sliding guide rail within the fixed disk, with jaws slidably connected within the guide rail. Support rods for supporting the workpiece are mounted on the jaws. A lead screw is located within the guide rail, with both ends rotatably connected to the ends of the guide rail. A drive gear is located at the end of the lead screw. A threaded sleeve meshing with the lead screw is located within the jaws. A lead screw drive motor is fixed within the rotary table, and a drive gear is fixed to the motor shaft of the lead screw drive motor. A second needle roller bearing assembly is located on the top of the rotary table, providing rolling support to the drive gear. The drive gear meshes with the drive gear.

[0029] like Figure 1 and Figure 3 The bottom of the support rod is fixed to the jaws by threads. A positioning plate is connected above the fixed plate through the support rods of each jaw. The positioning plate is provided with positioning grooves for the support rods to pass through. The end of the support rod is fixed to the positioning plate by a clamping nut. A support sleeve for supporting the inner wall of the workpiece is provided on the surface of the support rod.

[0030] like Figure 1 A rotating groove is provided on the surface of the rotating base, and a first needle roller bearing assembly is provided in the rotating groove.
